| 摘 要： | 锚杆参数的合理选择对隧道初期支护的稳定性具有重要意义.考虑隧道浅埋偏压的地质特性,采用了双侧壁导坑法,山内而外进行侧洞开挖,对浅埋偏压公路隧道的初期支护进行了数值模拟.分析了不同横阳间距和锚杆长度下,地表沉降、拱顶沉降、墙腰收敛值的变化规律,从而给出锚杆参数的合理值.

| Abstract: | Choosing reasonable rockbolt parameters has important significance for the stability of the tunnel primary support.The method of double side excavation was adopted for the tunnel primary support numerical simulation considering the geological properties of the bias tunnel,it was excavated from the inside hole to the outside hole.The rockbolt parameters was reasonably derived from the analyse of variety regularity about the different circumferential space,different rockbolt length,ground settlement,crown set... |
